Abstract

Invention m. used in vehicles and improves reliability by simplifying construction. During deceleration, the pressure in the control cavity 8 drops, the rod 9 is lowered and the condensate through the gap between the collar 11 and the ring 13 is ejected into the hole 14. After the deceleration stops, the cavity is connected to the receiver. 1 il. SL with SP about with

Description

113 /

This invention relates to devices for draining condensate from pneumatic systems, for example from air receivers of a brake system of a sports vehicle.

The purpose of the invention is to increase reliability by simplifying KOHCTpyKi Ht,

The drawing shows a condensate trap;

The steam trap for pneumatic systems includes a housing 1 with a clamp 2. The lid 2 has an air inlet 3 connected to the receiver 4. Between the lid 2 and the housing 1 there is a diaphragm 5 with a return spring 6 that forms a team 7 and controls 8 cavities. Control cavity 8 is connected to the pneumatic system main line. On the diaphragm 5 a hollow rod 9 is fixed, placed in the drain cavity 10. On the rod 9 there is an annular collar 11, which is a shut-off element of the exhaust valve. Above the shoulder 11 in the annular groove 12, formed in the wall of the drain cavity 10, an elastic ring 13 is installed, which is the seat of the exhaust valve. The condensate is carried out through the outlet 14. A handle 15 is attached to the end of the rod 9 to force the condensate to drain. In the rod 9 is made of radial through holes 16.

Compressed air from the receiver 4 flows through the inlet opening 3 into the collecting cavity 7 and into the control cavity 8. Condensate from the collecting cavity 7 through the hollow rod 9 and through the holes 16 flows into the drainage cavity 10. Under the action of the spring 6, the 9 9 are held in top position Editor A.Makovska

NIN, shoulder 11 is pressed to the ring 13. When the vehicle is braked, compressed air from the control cavity 8 is released into the atmosphere. The pressure in the cavity 8 drops, the rod 9 is lowered, the Condensate through the gap between the collar 11 and the ring 13 is discharged by compressed air into the hole 14. After

By stopping the stop, the control cavity 8 communicates with the receiver, the pressure in it increases, and the diaphragm 5 returns the rod 9 to its initial state. Burt 11 is pressed against the valve 15 of the control unit 13, the drainage of the condensate is stopped.

Claims (1)

Invention Formula A steam trap for pneumatic systems, comprising a housing with an outlet and a drain cavity in the lower part, a cover with an inlet opening, located between the cover and the housing, a diaphragm forming between 25 the assembly and control cavities, respectively, the latter being connected to pneumatic system lines, mounted on the diaphragm of the polm rod, placed in the drain cavity 30 of the valve and seat valve on the exhaust valve, which is soothed with the fact that, in order to increase reliability by simplifying the design, the outlet valve body is made in the form of an annular collar of the stem, the seat is in the form of an elastic ring placed above the collar and installed in an annular groove made in the wall of the drain cavity, and radial through holes are made above the collar, telling the team and. drain cavity. 35 40
